Men's merino base layer Bergans Inner:Pure Merino Long Sleeve Men Black 2025

Inner:Pure Merino Long Sleeve is a high-tech thermal underwear made of merino wool, designed for maximum comfort, warmth, and elasticity for every mountain adventure. The men's shirt is made from 100% high-quality merino wool with a fine knit and a fiber thickness of 18.5 microns.

After several years without a specialized thermal underwear line to succeed the bestselling Fjellrapp, Snoull and Akeleie, Bergans is introducing the brand new Inner: series starting in 2024. This series features lightweight, warm tops and bottoms crafted from fine and very pleasant-to-the-touch materials. The Inner: series includes several options:

• Inner:Lightweight - breathable thermal underwear sets designed for summer adventures in the high mountains.
• Inner:Heavy - Designed for the coldest months of the year.
• Inner:Dual - Double-layered thermal underwear that combines merino wool with synthetic materials, which extends the garment's lifespan and allows it to be worn by individuals with skin sensitive to wool.

Inner:Pure is made of 100% merino wool.

Merino wool has the ability to regulate body temperature and adapt depending on the intensity of physical activity, making it an excellent material for clothing designed for hiking, running, and cycling. During longer routes, athletes go through different stages, and this is particularly noticeable on uneven terrain with frequent changes between ascents and descents. The varying terrain requires different paces and levels of effort depending on the trail's profile. Merino wool does not retain unpleasant odors and continues to provide warmth even when wet, which is inevitable during intense workouts.
